    When it comes to cpu coolers this thing is great. It keeps my 6700k at a solid 55 degrees after hours of stress. Only recommendation would be to upgrade the fans or add additional push fans.

    My computer started crashing when gaming, It is a 5820k with a light overclock. I never really checked the Temps but after installing some software I saw my cpu was reaching 92°c! I immediately found the culprit, my cheap asetek water cooler was not cycling the coolant, the radiator was cool to the touch. I replaced it with this corsair and my Temps never go over 44°c under load. Have had no issues now 6 months later and the temp monitor software it comes with is useful and cool looking.

    My PC started to overheat. Cleaned the current CPU cooler and fan but still had the overheating issue (PC would shut down). Reviewed this unit from Best Buy online and decided to purchase. Was a good choice. Install instructions were easy to follow. Included adaptor kits to install on different CPU units/motherboards. It is big and could cause fit issues if you have a small case. I have a bigger gaming case so had no issue making it fit in mine. CPU now averages around 55-60 degrees.

    Works great but I would warn you to have a large case to fit the cooler and dual 120mm fans inside. It dropped my CPU temp by 15 degrees easy allowing me to overclock my CPU a get another few years out of my desktop.

    This thing is a beast. I would recommend measuring your case before buying this as it is pretty huge. We had to drill a few hole into the case we installed it in to make it work but I'm very happy with it. There are drivers/software you can download from the mfgr site for this as well to control all the components. It does have thermal paste already preapplied as well. Ive not had a single issue with overheating since I've had this unit and have both my CPU and GPU overclocked.

    After looking at aio coolers for a few months i fonally decided to go liquid cooling and overclock my i5 4690k. Its at 4.4ghz and stays cool even when gaming and multitasking, right around 60c is as high as ive seen the temps go. Usually hangs out around 52c when gaming. I was able to get this to fit in my corsair mid tower by removing the hard drive bay. I bought a 5.5 to 3.5/2.5 adapter since i removed the hd cage. It looks even better than i had imagined and cools very well.

    Once again Corsair delivers excellent cooling capacity but this time they have decreased the fan noise drastically. This keeps my PC at idle around 28 Celsius, and under load ~48-50 Celsius. This is as mentioned much quieter than the original H100i which was the only downside to that cooler. If you are looking for an easy to use AIO cooler then this is a great choice. Easy to install, great software to monitor and control your system and great temps.

    This was moderately easy to install, but the case you have determines the ease of installation. I thought it would be nice and quiet, but when I start getting into heavy use in certain areas while playing World of Warcraft on the highest setting, this thing sound like a mini jet engine spooling up. It also pulls dust and debris into the case like a vacuum cleaner, so make sure you have filters on your case. I noticed the dust issue when it started throwing dust out of the case and onto the wall, it's that much wind. I would have given it 5 stars if it was not so noisy, or if they had at least mentioned this on the box.
